Recombinant Human IRF5-11R Protein

Product Name: Recombinant Human IRF5-11R Protein
Catalog #:  HTF-2392
Manufacture:  LD Biopharma, Inc.

Human interferon regulatory factor 5 (IRF5) gene encodes a member of the interferon regulatory factor (IRF) family, a group of transcription factors with diverse roles, including virus-mediated activation of interferon, and modulation of cell growth, differentiation, apoptosis, and immune system activity. Members of the IRF family are characterized by a conserved N-terminal DNA-binding domain containing tryptophan (W) repeats. Alternative promoter use and at least 6 alternative splicing result in at least 6 isoform variants, and a 30-nt indel polymorphism (SNP rs60344245) can result in loss of a 10-aa segment.

Full-length human IRF5 cDNA (497aa, Isoform-I) was constructed with codon optimization using gene synthesis technology and expressed with a small T7-His-TEV cleavage site Tag (29aa) fusion at its N-terminal and 11 arginine (11R) tag at its C-terminal. It was expressed in E.coli as inclusion bodies. The final product was refolded using our unique “temperature shift inclusion body refolding” technology and chromatographically purified.
